The 5 Best Ecommerce Platforms for Large Companies

Choosing the right ecommerce platform is critical for large businesses needing scalable tools, multichannel selling and strong design flexibility. Our in-depth research and testing found Shopify to be the best overall platform for large companies, closely followed by Wix.

To save you time and resources, we’ve tested the leading platforms ourselves, evaluating their sales features, design tools, inventory systems and multichannel capabilities. These are the features that matter most to large companies aiming to grow fast and stay competitive.

Below, you’ll find a clear overview of the top five best ecommerce platforms for large businesses in 2025, including in-depth reviews and guidance to help you find the right fit.

Shopify: Best Scalable Ecommerce Platform for Large Businesses

Shopify is the most well-rounded platform in our research, combining robust design tools with advanced sales features, making it ideal for large businesses looking to scale across channels and regions.

What makes Shopify a great ecommerce platform for large businesses?

Shopify leads the pack for large companies in part because of its powerful design flexibility and advanced sales features.

Namely, it outperformed every other platform in our testing for product merchandising and checkout customisation, featuring standout tools such as customisable product pages, multiple payment options and advanced discounting rules.

Businesses can tailor the entire customer journey, from the homepage to the post-purchase experience, to suit their complex sales strategies and brand needs.

Its strong performance in multichannel selling also makes it ideal for enterprise-scale growth. Shopify allows seamless integration with marketplaces (like Amazon and Walmart), social platforms (including Facebook, TikTok and Instagram) and even offline sales channels via Shopify POS, something platforms like Squarespace and Square Online can’t match to the same depth.

The platform’s rich app ecosystem means that large businesses can build out highly bespoke functionality, including advanced automation tools, wholesale pricing and loyalty programs.

How could Shopify improve as a large business ecommerce platform?

While Shopify ranked top overall, it wasn’t without drawbacks. In our user testing, some participants noted that designing a storefront felt less intuitive than with Wix or Squarespace. Shopify also lags slightly behind those platforms in visual design quality out of the box, often requiring apps or developer tweaks to reach the same aesthetic polish.

Another potential downside could be its dependence on third-party apps for core functionality. Features like subscription selling or customer account customisation often require extra plugins, which can increase monthly costs and introduce additional complexity. Large businesses with little time and tight margins might appreciate an easier, all-in-one solution instead.

What other key features does Shopify offer for ecommerce?

• Shopify Plus: A dedicated enterprise-tier plan with improved customer support, custom workflows, and scalable infrastructure.
• Advanced reporting: Drill down into sales, customer data, and product performance.

• Global commerce: Built-in tools for localised currencies, duties and tax collection in 175+ countries.
• Staff permissions and multi-location inventory: Ideal for managing complex logistics across larger teams.

Shopify pricing

Similar to BigCommerce, one of Shopify’s three price plans is aimed at large companies, while it also offers a bespoke plan, Shopify Plus, for businesses generating £1,500 or more per month in revenue.

Wix: Best Ecommerce Platform for Large Businesses Prioritising Design

Of all the platforms we tested, we found Wix offers unmatched creative control and intuitive tools for aesthetics, making it the top choice for large businesses focused on branding and visual presentation.

What makes Wix a great ecommerce platform for large businesses?

Wix ranks just behind Shopify overall. However, that difference is less than half a percentage point, and Wix also outperforms every provider for design features, including Shopify. That makes it a strong contender for large businesses that prioritise brand identity and customer experience, and an excellent alternative to Shopify, in our view.

It offers an extensive library of professionally designed templates, advanced mobile editing and full creative control without needing to touch code. Features like section overlays, custom animations and parallax scrolling give Wix a clear edge in visual flexibility, which platforms like BigCommerce and Square Online lack entirely.

It also scored highly for sales features, particularly for product display and custom shipping options. Wix supports extensive product variant options, automated tax rules and granular shipping settings, making it well-suited for managing large inventories.

It’s built-in SEO for ecommerce patterns and custom checkout flows further support businesses with complex or regionalised needs. Large businesses can also take advantage of Wix’s multichannel selling, albeit its variety and extent can’t match Shopify’s offering. Read our Wix ecommerce pricing roundup for more information on costs.

How could Wix improve as a large business ecommerce platform?

Despite its strengths in design and visual merchandising, Wix does have some limitations when it comes to advanced commerce functionality.

Unlike Shopify and BigCommerce, it doesn’t offer native support for things like B2B selling (like separate pricing, quotes or login-restricted catalogues) or multi-currency support (Wix can change the displayed price to the user’s local currency, but not the sale price), which can be essential for global operations.

There are third-party tools to fill these gaps, such as SparkLayer for B2B sales and Global-e for multi-currency checkout, but they have additional costs.

In our user testing, Wix scored well for task completion and enjoyment, but some testers noted that managing advanced ecommerce workflows (like bulk product uploads or syncing inventory across channels) felt more manual. As such, for large companies with fast-moving stock or multiple sales streams, Wix may require more custom setup or third-party integrations than its rivals.

What other key features does Wix offer for ecommerce?

• Customisable checkout and cart rules: Tailor buyer experience without code.
• Wix Studio: A collaborative workspace for design teams managing multiple sites.
• SEO Patterns: Automate SEO across product and category pages.
• Wix Analytics: Built-in sales and customer tracking, including abandoned cart reports.

Wix pricing

Wix offers a 14-day free trial period and three ecommerce-specific plans. The most suitable plan for large companies is the Business VIP plan (remember you can install the ECWID app for extra ecommerce functionality).

Squarespace: Best Platform for Content-Driven Large Businesses

Combining beautiful design with rich content capabilities, Squarespace is a superb choice for large businesses selling services or subscriptions alongside products.

What makes Squarespace a great ecommerce platform for large businesses?

Squarespace performs strongly in our testing for design features, ranking just behind Wix. It offers sleek, modern templates and intuitive drag-and-drop controls that make it easy to create polished storefronts without design expertise.

For large businesses, the ability to build visually consistent landing pages, product collections and branded checkout experiences can help reinforce customer trust and improve conversion.

In terms of sales features, Squarespace supports digital and physical products, subscription selling and basic discounting rules. While it doesn’t match Shopify or Wix in overall sales flexibility, it does provide robust inventory tracking, automated tax calculations and multi-step checkout flows that suit medium-to-large catalogues.

It’s particularly strong for content-driven businesses that also sell online, such as media brands, publishers or service providers with ecommerce add-ons.

How could Squarespace improve as a large business ecommerce platform?

Where Squarespace falls short for large businesses is in its limited sales and operational scalability.

Unlike Shopify or BigCommerce, Squarespace lacks features like multi-currency support, custom user roles or native integrations with major third-party logistics (3PL) providers. Its app marketplace is also more limited, making it harder to expand functionality for wholesale pricing, advanced analytics or multi-location stock management.

In our user testing, Squarespace scored well for both task completion and task enjoyment, meaning users found the platform pleasant to use, but this ease of use comes at the expense of enterprise depth. For visually rich sites with modest operational complexity, Squarespace is a great fit – but the largest-scale ecommerce operations out there may find they outgrow its capabilities down the line.

What other key features does Squarespace offer for ecommerce?

• Integrated scheduling tools (Acuity): Ideal for service-based ecommerce.
• Flexible product blocks: Easily embed products in blog posts or landing pages.
• Built-in analytics: Track sales, traffic and conversion without external tools.
• Subscription product support: Sell memberships or recurring items out of the box.

Squarespace pricing

Our pick for the best Squarespace tier is the Basic Commerce plan, costing £23 per month. The other two plans on offer are the Business plan, costing £17 per month, and the Advanced Commerce plan, priced at £35 per month.

Square Online: Best for Large Businesses With Physical Retail Stores

Square Online is the easiest way for large businesses with physical locations to bring their store online, thanks to built-in POS integration and synced inventory management.

What makes Square Online a great ecommerce platform for large businesses?

Square Online’s biggest advantage is its tight integration with Square’s point-of-sale (POS) ecosystem, making it a practical choice for large retailers with physical storefronts. Especially since you can open up a free ecommerce platform with Square.

Businesses that already use Square terminals or in-person payment tools will benefit from real-time syncing of inventory, orders and customer data between online and offline channels. That’s a feature more fragmented on platforms like Wix or Squarespace, which don’t have these internal payment processing links.

Its sales features are solid for transactional efficiency: Square Online supports click-and-collect, kerbside pickup and time-based delivery slots, all useful for retailers managing high-volume or local fulfilment.

Bulk product uploads and advanced tax rules are available too, though not as advanced as those found in Shopify or BigCommerce. For businesses already in the Square ecosystem, it offers a fast, centralised solution for scaling online.

How could Square Online improve as a large business ecommerce platform?

Square Online scores lowest among the five platforms for design features. While its templates are mobile-optimised and clean, design flexibility is limited, especially compared with Wix or Squarespace.

You’re restricted in how much you can customise layouts, animations or even basic branding elements without custom code or developer input. If you’re a large company, these latter two options make out just fine, but it’s something to note if you were thinking of making swift A/B design changes.

Elsewhere, in our user testing, Square Online had the lowest scores for both task completion and task enjoyment. Users found the editor clunky, especially when trying to implement complex store features or custom pages.

It also lacks native support for large-scale ecommerce needs like multi-currency pricing, B2B workflows or advanced merchandising, limiting its appeal to more straightforward retail operations.

What other key features does Square Online offer for ecommerce?

• Seamless POS integration: Syncs inventory and payments across channels, including hardware like Square readers and terminals.
• Flexible fulfilment tools: Supports pickup, local delivery, and appointment scheduling.
• No monthly fees on starter plan: Great for testing new sales models at low risk.
• Built-in tipping, donations, and service charges: Useful for hospitality and service-based businesses.

Square Online pricing

Our top recommendation for Square Online is the Plus plan, which offers excellent value for growing retail businesses at £20 per month when billed annually. Square also offers a Free plan with essential features and a more advanced Premium plan for £64 per month, best for high-volume sales and lower transaction fees.

BigCommerce: Best for Large Businesses After International Growth

BigCommerce stands out for its powerful native sales tools, particularly for complex or high-volume ecommerce operations, making it ideal for large-scale and B2B sellers who need features like customer segmentation, bulk pricing and multi-currency support.

What makes BigCommerce a great ecommerce platform for large businesses?

BigCommerce offers robust tools for multi-currency pricing, customer group segmentation, B2B pricing tiers and custom shipping logic, all without relying on third-party apps. This gives it an edge over Wix, Squarespace and Square Online for large businesses with global or wholesale operations.

It also supports a headless commerce model, allowing businesses to separate the front-end customer experience from the back-end commerce engine. This makes it highly adaptable for custom storefront builds and integrations, and therefore an ideal choice for large-scale brands with in-house dev teams (unlike Square Online).

While not as beginner-friendly as Shopify or Wix, in this sense, BigCommerce is powerful for businesses that value control over extensibility.

How could BigCommerce improve as a large business ecommerce platform?

BigCommerce underperforms in design features compared with every other provider on this list.

While it allows custom HTML/CSS and theme editing, its default templates are less modern and flexible than those offered by Wix or Squarespace. Without developer support, many businesses will find it hard to achieve the same polish or creative branding as they could on more design-oriented platforms.

It also scored low for task enjoyment and had a relatively modest task completion score in our testing. Users found it functional but less intuitive, especially when navigating its backend UI or attempting basic storefront edits. For companies with strong tech teams, this won’t be a barrier, but for others it could slow time to launch.

What other key features does BigCommerce offer for ecommerce?

• Native B2B tools: Custom pricing, account approval workflows and purchase order support.
• Multi-storefront management: Run and manage multiple brands or regional sites from one dashboard.
• Open API ecosystem: Enables deep integrations with enterprise resource planning (ERP), customer relationship management (CRM) and fulfilment platforms.
• High scalability: Built to support thousands of SKUs, high traffic and global operations without plugins.

BigCommerce pricing

BigCommerce offers a 15-day free trial period and three price plans, with the Pro plan aimed at large companies. It also offers an Enterprise plan for businesses earning over £300,000 per year, with custom pricing.

It’s worth noting that BigCommerce is the only platform on this page that requires certain revenue brackets for your business to qualify for each plan.

Ecommerce Platform Buying Guide for Large Businesses

When selecting an ecommerce platform for a large company, focus on these four key areas:

Sales features

Look for built-in tools that support high-volume sales: inventory tracking, product variations, abandoned cart recovery and multichannel selling. Platforms like Shopify and BigCommerce are good options in this regard.

Design flexibility

Your site needs to reflect your brand. Wix and Squarespace offer highly customisable templates and drag-and-drop editors for full creative control.

Scalability and international reach

For growing businesses or international operations, prioritise features like multi-currency support, multi-storefront capabilities and strong integrations. BigCommerce and Shopify are the leaders in this area.

Ease of use and team collaboration

Consider how intuitive the platform is for large teams to manage. Squarespace ranks highest for task enjoyment, while Wix strikes a strong balance between usability and functionality.

It’s worth noting that no single platform fits every business entirely. We suggest using this brief guide to match your needs with the provider that best aligns with your growth plans, complexity and internal resources.
